Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbines, and in particular relates to a wheel-rail type wind turbine power generation device capable of remote detection. Background Art

[0002] The concept of applying the Magnus effect to wind power generation was first proposed in 1933, when American engineer Madaras conceived a large wind turbine experimental plan. The plan placed cylindrical blades on a wheel-rail trolley connected front and back, and used a motor to drive the blades to rotate. The Magnus lift generated by the incoming wind drove the wheel-rail trolley to run along the track, and the wheels rolling on the track drove the generator to rotate and generate electricity.

[0003] Domestic and foreign scholars have been continuously researching Magnus wind turbines. Scholar Scarpa designed a variable-section Magnus wind turbine, designing the outer side of the blade to be bubble-shaped. Under certain wind speed and cylindrical blade speed, this design significantly improved the tip speed ratio of the outer side of the blade and the functional conversion ability of the wind wheel; the Magnus wind turbine with spiral fins developed by Japan's MECARO company can generate lift through the interaction between each rotating cylinder and wind force to drive the generator to generate electricity. The wind turbine is designed based on the surface form of the rotating cylindrical blade, which further improves the efficiency of wind energy utilization; Sun Ying established a mathematical model of a vertical axis cylindrical blade wind turbine, obtained the factors affecting the aerodynamic performance of the blade, and conducted aerodynamic performance experiments on the blade, laying the foundation for improving the wind energy utilization rate of the whole machine;

[0004] The Chinese patent application publication number CN113898526A discloses a wheel-rail type wind turbine structure and its operation method, which drives the rotor blades installed on each power generation trolley to rotate at a predetermined direction and speed through a reversing center in a time-sharing manner, inducing the blades to generate a Magnus effect force in the wind field that can drive the power generation trolley to continuously run along a circular track, and the wheels of the trolley drive the power generation device to generate electricity; during the reversal of the rotor blades, the excess load capacity of the motor drives the flywheel to store energy, and the inertia of the free rotation of the rotor is stored by the spring and released to it after the rotor blades are reversed; the number of starting and stopping the power generation device can expand the wind range of the wind turbine;

[0005] In order to detect wind turbine faults in current technology, various equipment (such as speed meters, power generation, and electric energy metering devices) need to be installed to measure the wind turbine. These devices can easily cause resistance to the operation of the wind turbine and affect the working performance of the wind turbine. Utility Model Content

[0006] The utility model aims to provide a wheel-rail type wind turbine power generation device capable of remote detection, which can achieve the goal of remotely detecting whether a wheel-rail type wind turbine has a fault and has little influence on the operation of the wheel-rail type wind turbine.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A wheel-rail type wind turbine power generation device capable of remote detection, comprising a main engine, a wheel-rail type wind turbine and a rotation speed measuring device;

[0009] The wheel-rail wind turbine comprises an annular track, on which three power generation trolleys are mounted, and the three power generation trolleys are all mounted with vertically arranged cylindrical rotor blades via rotating rods, the three rotating rods are connected via a trolley connecting frame, and the rotating rods are rotatably connected to the trolley connecting frame;

[0010] The speed measuring device is located at the center of the circular track, a measuring terminal is installed on the speed measuring device, an electric control connecting terminal is installed on the measuring terminal, a connecting terminal is installed at the center of the trolley connecting frame, and the electric control connecting terminal can be connected to the connecting terminal;

[0011] The rotation speed measuring device, the power generating trolley and the electric control connecting terminal are all electrically connected to the main machine.

[0012] Furthermore, the electrically controlled connecting terminal comprises an electrically controlled vertical movable member mounted on the measuring terminal, and a connecting piece vertically opposite to the connecting terminal is mounted on the electrically controlled vertical movable member.

[0013] Furthermore, the vertical moving part includes a lower bracket fixedly connected to the measuring end, two guide rods are vertically slidably connected to the lower bracket, the upper ends of the two guide rods are fixedly connected to the connecting plate, a first electromagnet is fixedly connected to the lower bracket, and a second electromagnet is fixedly connected to the connecting plate, and the first electromagnet and the second electromagnet magnetically repel each other when energized.

[0014] Furthermore, both ends of the connecting piece are fixedly connected with a third electromagnet, and when the third electromagnet is energized, it magnetically adsorbs the connecting terminal, and the horizontal cross-section of the connecting terminal is circular.

[0015] Furthermore, the trolley connecting frame is located at the lower side of the cylindrical rotor blades.

[0016] The technical effects achieved by the utility model are:

[0017] (1) The utility model is a wheel-rail type wind turbine generator capable of remote detection. When the device is in normal use, the electric control connection terminal and the connection terminal 6 are separated, which does not affect the normal operation of the power generation vehicle 2 and the cylindrical rotor blades 3, and does not increase the resistance thereto.

The direction of the lift is perpendicular to the wind force and complies with the principles of fluid mechanics, pushing the power generation vehicle 2 forward along its circular track 1. During the movement, the wheels of the power generation vehicle 2 rotate, inputting rotational kinetic energy into the power generation equipment, thereby achieving the purpose of power generation;

[0018] When the device needs to be tested, the female electric control connection terminal and the connection terminal 6 are connected, and then the rotation speed of the trolley connection frame 5 is detected by the measuring terminal 8, so that the movement of the power generation trolley 2 can be known. By determining whether the rotation of the trolley connection frame 5 matches the power generation of the device, whether there is a fault in the operation of the detection device, and the detection result is transmitted to the host;

[0019] By setting a remotely controllable rotation speed meter 7 and an electrically controlled connection terminal to measure the movement of the power generation vehicle 2, the goal of remotely detecting whether a wheel-rail wind turbine has a fault can be achieved. The structure is relatively simple and has little impact on the operation of the wheel-rail wind turbine. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0027] like Figure 1 As shown, a wheel-rail type wind turbine power generation device capable of remote detection comprises a main engine, a wheel-rail type wind turbine and a rotation speed measuring device 7;

[0028] The wheel-rail wind turbine comprises an annular track 1, on which three power generation trolleys 2 are mounted, and the three power generation trolleys 2 are all mounted with vertically arranged cylindrical rotor blades 3 through rotating rods 4, and the three rotating rods 4 are connected through a trolley connecting frame 5, and the rotating rods 4 and the trolley connecting frame 5 are rotatably connected;

[0029] Among them, the power generation vehicle 2 includes a vehicle body, wheels installed on the vehicle body and power generation equipment connected to the wheels. When the wind speed in the wind field is stable and meets the requirements for normal operation of the wind turbine, a power generation vehicle 2 is running on the circular track 1 facing the wind (or leeward), and the cylindrical rotor blades 3 thereon obtain sufficient Magnus lift from the rotation in the wind field. The direction of the lift is perpendicular to the wind force and complies with the principles of fluid mechanics, pushing the power generation vehicle 2 forward along its circular track 1. During the movement, the wheels of the power generation vehicle 2 rotate, inputting rotational kinetic energy into the power generation equipment, thereby achieving the purpose of power generation.

[0030] The above part belongs to mature existing technology, and will not be described in detail in this technical solution. The core of this technical solution is that the speed measuring device 7 is located at the center of the circular track 1, and a measuring terminal 8 is installed on the speed measuring device 7. The measuring terminal 8 is equipped with an electric control connecting terminal mother, and the center position of the trolley connecting frame 5 is equipped with a connecting terminal 6, and the electric control connecting terminal mother can be connected to the connecting terminal 6;

[0031] At this time, when the device is in normal use, the electrically controlled connecting terminal mother and the connecting terminal 6 are separated, which does not affect the normal operation of the power generation trolley 2 and the cylindrical rotor blades 3, and does not increase resistance thereto. When the device needs to be tested, the electrically controlled connecting terminal mother and the connecting terminal 6 are connected, and then the rotation speed of the trolley connecting frame 5 is detected by the measuring terminal 8, and the movement data of the power generation trolley 2 can be known. The movement of the power generation trolley 2 is related to the power generation of the power generation trolley 2 when the power generation trolley 2 is working normally. By determining whether the rotation of the trolley connecting frame 5 and the power generation of the device match, it can be detected whether there is a fault in the operation of the device. The speed measuring device 7, the power generation trolley 2 and the electrically controlled connecting terminal mother are all electrically connected to the main machine, so that the speed measuring device 7, the power generation trolley 2 and the electrically controlled connecting terminal mother can be controlled on the main machine, and the output data of the speed measuring device 7, the power generation trolley 2 and the electrically controlled connecting terminal mother, such as the power generation of the power generation trolley 2 and the speed value measured by the speed measuring device 7, can be received.

[0032] The electrical connection between the speed meter 7, the power generation vehicle 2, the electric control connection terminal and the host can be a wire connection or a 4G / 5G signal connection.

[0033] The electric control connection terminal mother can be an electric clamp to clamp the connection terminal 6 to complete the connection between the electric control connection terminal mother and the connection terminal 6. Figure 1-3 As shown, the electrically controlled connecting terminal mother includes an electrically controlled vertical movable part installed on the measuring terminal 8, and a connecting piece 10 vertically opposite to the connecting terminal 6 is installed on the electrically controlled vertical movable part. When the electrically controlled vertical movable part drives the connecting piece 10 to rise to abut against the lower side of the connecting terminal 6, the connection between the connecting piece 10 and the connecting terminal 6 can be completed, and the rotational speed of the trolley connecting frame 5 can be measured. When the electrically controlled vertical movable part drives the connecting piece 10 to move down to separate from the lower side of the connecting terminal 6, the separation of the connecting piece 10 and the connecting terminal 6 can be completed, and the operation of the rotational speed measuring device 7, the power generation trolley 2 and the electrically controlled connecting terminal mother is no longer affected.

[0034] like Figure 3-4 As shown, in order to reduce the excessive squeezing damage of the connecting piece 10 to the connecting terminal 6, the vertical moving part includes a lower bracket 9 fixedly connected to the measuring end 8, and two guide rods 11 are vertically slidably connected to the lower bracket 9, and the upper ends of the two guide rods 11 are fixedly connected to the connecting piece 10, so that the connecting piece 10 can slide vertically on the lower bracket 9, and a first electromagnet 12 is fixedly connected to the lower bracket 9, and a second electromagnet 13 is fixedly connected to the connecting piece 10. When the first electromagnet 12 and the second electromagnet 13 are energized, they repel each other magnetically, so that the lower bracket 9 can drive the connecting piece 10 to rise, and due to its non-rigid contact, it can reduce the excessive squeezing damage of the connecting terminal 6 by the connecting piece 10.

[0035] Moreover, in order to enhance the connection stability between the connecting piece 10 and the trolley connecting frame 5, the two ends of the connecting piece 10 are fixedly connected with a third electromagnet 14. The connecting terminal 6 can be made of iron or other magnetic materials. When the third electromagnet 14 is energized, it magnetically adsorbs the connecting terminal 6, so that the connection stability between the connecting piece 10 and the trolley connecting frame 5 is better, and the transmission effect is better.

[0036] In order to make it easier for the third electromagnet 14 to contact the connecting terminal 6, the horizontal cross-section of the connecting terminal 6 is circular, so that the third electromagnet 14 can always be located at the lower side of the connecting terminal 6 after the rotation is completed, and can directly contact the connecting terminal 6 when the third electromagnet 14 rises.

[0037] like Figure 1-2 As shown, in order to reduce the influence of the tachometer 7 and the electric control connection terminal on the wind force, the trolley connecting frame 5 is located on the lower side of the cylindrical rotor blade 3, so that the tachometer 7 and the electric control connection terminal can be located on the lower side of the cylindrical rotor blade 3 without blocking the wind force blowing toward the cylindrical rotor blade 3.

[0038] The working principle of the utility model is as follows: when the device is used normally, the electric control connection end mother and the connection terminal 6 are separated, which does not affect the normal operation of the power generation vehicle 2 and the cylindrical rotor blades 3, and does not increase the resistance thereto. At this time, when the wind speed in the wind field is stable and meets the requirements for the normal operation of the wind turbine, a certain power generation vehicle 2 is running on the windward (or leeward) circular track 1, and the cylindrical rotor blades 3 on it obtain sufficient Magnus lift from the rotation in the wind field. The direction of the lift is perpendicular to the wind force and complies with the principle of fluid mechanics, pushing the power generation vehicle 2 forward along its circular track 1. During the movement, the wheels of the power generation vehicle 2 rotate, inputting rotational kinetic energy into the power generation equipment, thereby achieving the purpose of power generation;

[0039] When the device needs to be tested, the female electric control connection terminal and the connection terminal 6 are connected, and then the rotation speed of the trolley connection frame 5 is detected by the measuring terminal 8, so that the movement of the power generation trolley 2 can be known. By determining whether the rotation of the trolley connection frame 5 matches the power generation of the device, whether there is a fault in the operation of the detection device, and the detection result is transmitted to the host;

[0040] In summary, this technical solution can achieve the goal of remotely detecting whether a wheel-rail wind turbine has a fault by setting a remotely controllable speed meter 7 and an electrically controlled connection terminal to measure the movement of the power generation vehicle 2. The structure is relatively simple and has little impact on the operation of the wheel-rail wind turbine.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
